하이브리드 상용트럭 에어 브레이크 챔버 요소부품의 구조적 해석 연구 A Study on Structual Simulation of Element Parts in Air Brake Chamber for Hybrid Commercial Trucks
pp.717-723
Air Brake chamber is a core fucntional part delivering the brake force to drum brakes in hybrid commercial trucks. This part needs to have leakage prevention and durability for reliable operation. As an actuator by air pressure, there has to be no air leakeage, and because it is operated with high tention power spring, there has high durable spring head, that contacted power spring directly. In this study, a spring head was designed new size on weak points structually and simulated by structual simulation program. And, a flange and body tighten by clamp ring was simlated structual deformation by assembly torque and inner pressure. As a result, new desgned spring head has structual stablilty over 1.7～14.7% and deformation is in proprotion to inner pressure but the assembly torque of clamp ring is not related to deformation.
